Method:Shake all ingredients apart from the Guinness.
Fine strain into a chilled 7oz punch glass. Add a small piece of hand cut ice, float Guinness on top and finish with nutmeg.
Notes:A drink created in homage to Gilbey Vintners who launched Redbreast Irish Whiskey in 1939. Redbreast today is an iconic member of the single potstill revolution and can be found in many of the best bars across the world. A wonderful mix of Guinness, single potstill whiskey and citrus.
